For a level whose second half consists entirely of wave spam, I had a lot of fun with this one. The clicksync-based first half of course feels good to play, and I thought it was fun finding a cool way to do the second half. (If anyone wants to try my idea, I clicked in eighth note patterns for the normal wave parts and either quintuplets (roughly) or fast triplets for the mini wave parts.) The deco is pretty cool as well; it uses the limitations of 1.9 to their fullest extent, making every part feel entirely different while still keeping the same rainbow motif.
